Advanced Transportation Management System Along The I-95 And Spaulding Turnpike CorridorsElectronic Message Signs And Cameras Being Installed

Motorists on Interstate 95 between the Massachusetts and Maine state lines, as well as along the Spaulding Turnpike from Exit 1 through Exit 16 in New Hampshire, will soon benefit from the installation of electronic message signs and closed circuit cameras aimed at improving incident response and work zone safety, and reducing traffic congestion.

The I-95 Advanced Traffic Management System (ATMS) project involves the installation of strategically located "Intelligent Transportation System" (ITS) devices along the 39-mile corridor that will be controlled by the Traffic Management Center (TMC) in Concord. Also included within the project area are field locations along NH Route 101, and US Route 4.

A total of three "Dynamic Message Signs" (DMS) are being installed along the I-95 corridor. Each DMS, at eight feet high and 26 feet wide, will be mounted on overhead sign structures, and used to convey important electronic traffic messages. Twenty-four closed circuit television cameras are being installed at strategic traffic locations along both the I-95 and the Spaulding Turnpike corridors. The cameras will be mounted on tall steel poles ranging in height from 65 to 90 feet.

The entire system will be connected via a point-to-point microwave radio communications system. The communication equipment will be installed either on independent steel poles or it will be co-located with the closed circuit cameras.

Transcore of New York City is the general contractor and designer for the $5.1 million design-build project. The electronic message signs and cameras are expected to be operational in early 2012.
